Benefits of technology
The patent describes a method, apparatus, and computer program product for identifying the type of vehicle driving over a road surface based on audio data collected from the vehicle. This can be useful for various applications such as government or regulatory agencies that maintain road networks, or for providing relevant information to drivers. The method involves analyzing the audio data to identify specific features, such as audio amplitude or frequency, and using a machine learning model to predict the vehicle's class. The audio data can be collected from the vehicle's wheels or from the road surface. The method can also include identifying map objects and providing information about them to the machine learning model. Overall, this technology can help improve the accuracy of identifying different types of vehicles on the road.
Problems solved by technology
However, these sensors currently on board vehicles do have limitations and do not collect all of the different types of information that would be useful in various applications.

A method, apparatus and computer program product are provided to identify the class of vehicle driving over a road surface based upon audio data collected as the vehicle drives thereover. With respect to predicting a class of a vehicle, audio data is obtained that is created by the vehicle while driving over the road surface. The audio data includes one or more audio frequency features and / or one or more audio amplitude features. The audio data including the one or more audio frequency features and / or the one or more audio amplitude features is provided to a machine learning model and the class of the vehicle that created the audio data is predicted utilizing the machine learning model. A method, apparatus and computer program product are also provided for training the machine learning model to predict the class of the vehicle driving over the road surface.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims benefit of U.S. Provisional Application No. 63 / 031,036, filed May 28, 2020, which is incorporated herein by reference in its entirety.TECHNOLOGICAL FIELD[0002]An example embodiment relates generally to a method, apparatus and computer program product for determining the class of a vehicle and, more particularly, for determining the class of a vehicle based upon audio data generated by the vehicle driving over a road surface.BACKGROUND[0003]Modern vehicles include a plurality of different types of sensors for collecting a wide variety of information. These sensors include location sensors, such as global positioning system (GPS) sensors, configured to determine the location of the vehicle. Based upon the location of the vehicle, a variety of navigational, mapping and other services may be provided for manually driven vehicles as well as the provision of navigation and control of autonomous or semi-autonomous vehicles...
